Severe Tropical Cyclone Narelle, category 4, is forecast to strengthen further tonight as it approaches the North West Cape.

Later tonight or early Friday, Narelle will turn towards the south, likely passing close to the North West Cape as a category 4 cyclone. Severe impacts will extend from the western Pilbara coast to the Gascoyne coast overnight, and then extending south to Denham during Friday.
On Saturday, Narelle is expected to be weakening as it moves quickly to the south southeast with impacts extending to the Central West and then further inland and south across the South West Land Division. During Saturday the strongest winds are expected to be on the eastern side of the system.

VERY DESTRUCTIVE WIND GUSTS up to 275 km/h may develop between Exmouth and Onslow later this evening as Narelle moves closer to the North West Cape, and then extend down the west coast to Cape Cuvier during Friday morning. Carnarvon could see wind gusts up to 200 km/h during Friday, and wind gusts up to 180 km/h could extend to Denham late Friday or early Saturday.
DESTRUCTIVE WIND GUSTS in excess of 125 km/h are occurring along the Pilbara coast between Mardie and Onslow, and are expected to extend west to Exmouth this evening, and south to Carnarvon and then to Denham and the Overlander Roadhouse during Friday. DESTRUCTIVE WIND GUSTS in excess of 125 km/h may extend to Kalbarri and inland parts later Friday and possibly as far south as Morawa Saturday morning.
GALES with DAMAGING WIND GUSTS to 120 km/h are occurring near the coast between Whim Creek to west of Onslow. Gales will develop west to Exmouth this evening, and then extend further south to Kalbarri and inland to the Overlander Roadhouse and possibly to Murchison during Friday. Gales may extend south to Jurien Bay and inland to Dalwallinu during Saturday morning.
HEAVY RAINFALL which may lead to FLASH FLOODING is possible in western parts of the Pilbara and Gascoyne as Narelle moves past. Areas of INTENSE RAINFALL that may lead to SEVERE FLASH FLOODING is likely to develop about the western Pilbara west of about Onslow overnight and Friday morning, before extending further south into the northwestern Gascoyne later Friday morning.
Coastal residents between Onslow and Denham are specifically warned of a DANGEROUS STORM TIDE as the cyclone moves south down the Gascoyne coast. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING.
